09fc6e22e5 all: use workingsetcache instead of fastcache
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.

eb2283a029 lib/storage: reduce too big maxMetrics in getTagFilterWithMinMetricIDsCountAdaptive
This should improve performance on inverted index search for big amount of unique time series
when big -search.maxUniqueTimeseries is set.

33ea2120c3 lib/storage: use unversioned keys for tag cache in extDB
Data in ExtDB cannot be changed, so it is OK to use unversioned keys for tag cache.
This should improve performance for index lookups over big amount of time series.

cf63669303 lib/storage: skip searching in extDB if it doesn't contain items for the given time range
This should improve inverted index search performance for big amount
of unique time series when the search is performed only on recent data.

7b6623558f lib/storage: skip adaptive searching for tag filter matching the minimum number of metrics if the identical previous search didn't found such filter
This should improve speed for searching metrics among high number of time series
with high churn rate like in big Kubernetes clusters with frequent deployments.
